WATER-PIPE RENOVATOR.

SPECIFICATION forming part of Letters Patent N 0. 717,572, dated January 6, 1903.

Application filed January 10, 1902. Serial No. 89,213. (No model.)

To all whom it may concern.-

Be it known that we, ROBERT W. HnLLoMs and LUKE S. BOYDSTON, citizens of the United States, residing at Watervalley, in the county of Yalobusha and State of Mississippi, have invented certain new and useful Improvements in VVater-Pipe Renovators; and we do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

Our invention relates to the class of pipe and main cleaners, and has for its object to provide a water-pipe renovator which will effectually remove all obstructions from pipes which are caused by the collection of grease, vegetables, leaves, &c., within the same.

With this object in view our invention consists in the novel construction of a pipe-renovator, as well as in the method employed.

Referring to the accompanying drawings, Figure l is a sectional view of our invention, showing its application to a stationary water-basin. Fig. 2 is an elevation of the renovator, and Fig. 3 is a detail perspective of the lower or bottom end thereof.

Like numerals of reference indicate the same parts throughout the several figures.

1 is the cylinder, having the cone-shaped bottom 2, upon which is formed the barrel 3,

which is provided with perforations 4 and which is provided with a flare 5 at the bottom thereof. Suitably secured to said flared portion in any approved manner is a flange or washer 6, of soft yielding material, pref:

erably of rubber and canvas. Slidingly secured around said barrel 3 is a collar 7.

8 indicates the piston, which is provided with a rod 9, upon which is formed a handle 10 of any suitable form or construction.

11 indicates a removable cap or top, which is provided with perforations 12.

Having thus described the several parts of our invention, its operation is as follows: We will suppose that the pipe leading from the stationary basin in Fig. 1 has become obstructed. The renovator is placed directly over the pipe and the collar 7 is raised, as shown in Fig. 3, and a small quantity of Water is allowed to run into the basin. The piston is then reciprocated several times in order to prime the same, and the collar is then lowered over the perforations 4:. The renovator is then held firmly over the top of the pipe and the piston is reciprocated, not in a manner which would force the obstruction down the pipe, because that is not the object aimed at, but the alternate vacuum formed or suction and force uses the water in the pipe to clear the pipe by first drawing the water up and then forcing it back, thereby loosening the obstruction, so that the same will be carried away when water is run into the pipe.

It may sometimes happen that the obstruction is formed so solidly that at first it is difflcult to operate the piston. 'In this event the collar 7 may be raised a trifle, so as to allow a slight ingress of air while reciprocating the piston, and thus loosen the obstruction gradually; otherwise the downward stroke of the piston might tend to damage weak parts of the pipe. After starting the obstruction the collar is then lowered, which will give the pipe the full power of the renovator.

Having thus f nlly described the operation of our invention, we do not wish to be understood as limiting ourselves to the exact construction as herein set forth, as various slight changes might be made therein which would fall within the limit and scope of our invention, and we consider ourselves clearly entitled to all such changes and modifications.

What we claim as new, and desire to secure by Letters Patent of the United States, is

1. In a water-pipe renovator, the combination with a cylinder and piston, of a barrel formed at the end of said cylinder, perforations in said barrel, a collar adapted to cover said perforations, a flared portion formed on said barrel, and a flange or washer of yielding material suitably secured to said flared portion, substantially as described.

2. In a water-pipe renovator the combination with a cylinder and piston of a flange or washer of yielding material secured below said cylinder, said renovator being provided with perforations above said flange or washer, and a collar adapted to cover said perforations, substantially as described.

In testimony whereof we ali'ix our signatures in presence of two-witnesses.
